Beyonce gave a surprise live performance of the national anthem at a press conference for the Super Bowl Thursday afternoon.

The singer came out and asked attendees to stand, then launched into an a cappella version of “The Star-Spangled Banner.” When she finished, she thanked everyone and said, “Any questions?”

Beyonce came under fire recently after a spokesperson for the U.S. Marine Band, which played backup for the singer at the presidential inauguration, reportedly said she had lip-synched the national anthem at the event. A spokesperson for the Marines told Speakeasy nobody in the group was actually in a position to know.

At Thursday’s press conference, a journalist asked about the controversy, and Beyonce said she “did not feel comfortable” taking the risk of singing live because she wasn’t able to rehearse with the orchestra, and due to the weather and other conditions. She said she instead sang along to a prerecorded track.
